Small 4MP. No, I would not recommend the Sony A7riv to anyone for more cropping room than a 42mp sensor. I can buy an external hard drive. Those are fairly large prints. For Raw files, you can specify how many bits of color data you want to record. Those raw files get pretty darn big. Still, the consensus is that 35mm is about equivalent to 12-20 megapixel digital images. There may be a pause for up to 2-3 seconds on my 2-year-old laptop. The maximum print size of the A7riii, utilizing those 42 megapixels printed at 300 dpi, would be 27X18. If you research film equivalent resolution, you won’t get a universal answer. amzn_assoc_marketplace = "amazon"; Figures assume size-priority JPEG compression. So while 5 megapixels sounds like a lot more than 3 megapixels, it actually only make a slight difference in print size. amzn_assoc_design = "in_content"; Size … The next step to the A7riv becomes even more astronomical, approximately 120mb uncompressed and 60mb compressed. Sony A7iii/A9: 300mm can become 450mm equivalent, Sony A7rii/A7riii: 300mm can become 600mm equivalent, Sony A7riv: 300mm can become 690mm equivalent, Display of the image in the LCD/EVF which requires some level of “processing”. amzn_assoc_asins = "B076TGDHPT,B07B43WPVK,B07D7K48TB,B07VGHW91J"; Something changed around 2012 and ever since: There was a split in the resolution wars. The A7Riv gives another 15% more cropability than the A7riii. Sony and Nikon both offered full frame camera variants in 24mp and 36mp varieties. Many of the people purchasing the Sony A7riv may want to think twice. But the more we push up resolution, we truly face diminishing returns. But many of us, when we upload our photos, will view them at extreme magnification. It can really add up. In contrast, shooting with the Sony A7iii/A9, I’d expect that hard drive space to last up to a full year. 10 megapixels proved sufficient for decent “normal” size prints but you could forget about detailed large prints or significant cropping. Real world difference? Other ramifications can be more frustrating. In other words, the A7riii gives you about 33% more “cropability” than the A7iii/A9. If you opt for 14 bits, which enables the file to contain more color data, understand that doing so increases the file size. Do you mean linear size, the resolution of the image, or its file size? Uploading/exporting the photos: Another bottleneck, whether you are exporting them as jpegs, writing to a CD, or uploading them to the internet. But for now.. 61mp… personally I’m out. amzn_assoc_ad_type = "smart"; If we examine it as focal length: Let’s use the Sony 70-300mm G lens. The 20 megapixel 1inch BSI sensor is used in a number of cameras, including the Sony Cyber-shot RX100 II, the Panasonic Lumix FZ1000, TZ100, and Canon Powershot G5X, G7X Mark II etc. Sony A7Riii, from imaging-resource: Excellent, detail-rich print up to 30 x 40 inches all the way to ISO 1600. An image may look great at normal viewing size, but as you magnify (or crop), the defects become obvious. So going from 24X36 to 40X60 may be a good jump for those that like to print large. However, at typical viewing distances for a print this large, you won’t notice any issues. Both images still have a fair amount of resolution left. It would be disingenuous to say that the 61mp of the Sony A7riv does not provide any benefit. The images are different, but are from the same session and I tried to use about the same framing, and situation, so we've similar files. At this size, you are pushing the resolving power of the 24-megapixel sensor, as you can see very subtle pixelation if you look really closely. Some people will claim that they can see the extra resolution even when downsized, we will test that out.. amzn_assoc_marketplace = "amazon"; Large 24MP. amzn_assoc_design = "in_content"; But not every image has to be printed at 300 dpi. Thus, you will only see the extra resolution as you maximize print sizes. It’s usually because most platforms on the web and social media don’t display images at full resolution. Download the perfect raw pictures. So when do you even see the full resolution of a high resolution sensor? Being honest with yourself, can you tell which came from the higher resolution camera? I’d expect to get many 10-15+ second delays with image rendering in Lightroom with the Sony A7riv. Maybe if you have the absolute sharpest lenses, nail absolutely perfect focus, you can get a beautiful 100% crop of a 61mp image. DNG files are typically about 20% smaller than a RAW file, which means you can store more of them on your computer. Personally, I am primarily working on a half-decent laptop I bought two years ago. amzn_assoc_asins = "B076TGDHPT,B07B43WPVK,B07D7K48TB,B07VGHW91J"; 1 mp extreme crop from Sony A7riii 42mp sensor, This blog particpates in Amazon’s Associate program and earns from qualifying purchases Lightroom also creates the previews, does some batch processing. Assume you have 250 free gigabytes. My 5DII RAW files (21MP) are between 22 and 30MP. The frustration of a lengthy pause, every time you apply an edit or magnify the image. The telephoto lenses beyond 300mm start to get rather large and heavy. And going to 61mp gets the viewer one small step closer, 24 inches. I’ll assume the latter. If you crop significantly AND print large, the advantages will start to magnify and be more obvious. The crop allowed plenty of megapixels to remain for fairly large printing. Thanks to Vladimir Gorbunov for preparing this very helpful chart: In this chart, we can see how resolution affects the pring pixel density at various sizes. So I would expect the A7riv will require extensive use of external hard drive. Depends on many factors and it’s not easy to compare analog film with digital megapixels. So realistically, who would benefit from all those extra megapixels? amzn_assoc_placement = "adunit0"; So while we estimated that cropability may increase from 1.5x to 2x to 2.3x, for this to be really effective, you need to be using the best lenses and proper technique. The ability to view extra fine details under extreme magnification is just a parlor trick, it doesn’t provide any real benefit to clients, family, friends, who are viewing the photos online or in print. Pixel peeping! 40 screens were possible with standard definition televisions but they weren’t popular because you had to be really far back for the image to look good. For the portraits, I used the Sony 100mm F/2.8 STF GM lens, an ultra sharp lens that left me confident of utilizing the higher resolution of the Sony A7riii.
